Bamowi: Battery Monitor & Temp

This app is designed to alert you on too high or too low battery temperature. Prevent your phone's battery from overheating or freezing by receiving a notification if its temperature exceeds a limit. Additionally, receive notifications on low battery level, and configure an alert level while charging to protect your battery from overcharging. The app collects and visualizes different data about your battery and the charging process, showing statistics and charts.

A simple, lightweight version of this app, without the statistics and charts is available here: https://play.google.com/store/apps/details?id=dev.bytesculptor.batterytemperaturestatus

🔋 Battery Data

• The battery temperature in the notification bar
• Get notifications for low battery level, too high or too low temperature and charging level reached
• The battery current, voltage and power in one card, with a live graph of the current
• Today’s screen time and how often the screen was turned on
• Lowest and highest reached values of temperature, level, voltage, current, and power with a timestamp
• Choose between degree Fahrenheit and Celsius

📈 Charts

• The changes in a graph over the past days
• Configure the graph by choosing level, temperature and voltage alone or in two graphs together
• Separate graph for battery current
• Zoom and scroll the graphs

💚 Battery health

• Estimated battery capacity and health, so you can track how your battery ages over time
• Screen time per day with a trend line (one week; up to four weeks in PRO)

📶 Statistics & Timeline

• All charging events with duration, charging difference and speed in a timeline.
• Charging statistics insights (number of charges, start/stop level, speed, total charges, etc.)

🔅 App Widgets

• Two widgets: a ring widget for the battery level, and a universal widget
• The universal widget shows battery level, temperature, voltage, screen time and time left – you choose which, with the level as a ring or as text
• Free choice of background and text color, adjustable font size, and it adapts to any size you give it

🏆 PRO Features

• Data logging for charts is 14 days instead of 3 days
• Configure the content of the status notification
• Configure the status icon (temperature or level), with or without unit
• The Timeline shows the following values of each charging event: temperature range, max current, max power, max voltage, estimated capacity (on +60% charging events)
• Export the charts data, charging data, estimated capacity and battery current to a .csv file for your own further analysis
• See the full list of all capacity measurements, and delete single entries
• Set a daily screen time limit and get a notification once you exceed it, with today’s progress on the home screen
• Capacity chart over one year or all time, with the monthly capacity trend
• Screen time chart over up to four weeks, and today’s screen time hour by hour

Although the app has to run permanently in the background to operate reliably, it has a very low energy consumption. On all our test devices it is less than 1%.

The operating system sometimes stops the app. In this case, the widget is no longer updated, notifications are not sent, and no data is logged. To prevent this, Bamowi should be excluded from any battery saver app. If you use a task-killer app, Bamowi must be excluded to work properly.

Some manufacturers restrict heavily apps in the background. It is possible that this app doesn't work reliably on some models from Samsung, Oppo, Vivo, Redmi, Xiaomi, Huawei, Infinix and Ulefone. Please check the Help section of the app for further instructions.
